This pilot study describes a relationship between insulin resistance and μ-opioid neurotransmission in limbic appetite and mood-regulating regions in women with polycystic ovary syndrome (PCOS), suggesting that insulin-opioid interactions may contribute to behavioral and reproductive pathologies of PCOS. We found that [1] patients with PCOS who are insulin-resistant (n = 7) had greater limbic μ-opioid receptor availability (nondisplaceable binding potential) than controls (n = 5); [2] receptor availability was correlated with severity of insulin resistance; and [3] receptor availability normalized after insulin-regulating treatment.
这项初步研究描述了胰岛素抵抗与多囊卵巢综合征(PCOS)女性边缘食欲和情绪调节区域的μ-阿片类神经递质传递之间的关系,表明胰岛素-阿片类相互作用可能导致 PCOS 的行为和生殖病理。我们发现,[1]胰岛素抵抗的 PCOS 患者(n = 7)比对照组(n = 5)具有更高的边缘μ-阿片受体可利用性(不可置换结合潜能);[2]受体可利用性与胰岛素抵抗的严重程度相关;[3]在胰岛素调节治疗后,受体可利用性恢复正常。
